Title: Super scalar processor
Inventor: TAKAYAMA KOICHI
IPC: G06F11/14
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of system performance, and to attain restoration from any failure. SOLUTION: For example, when this device is provided with four instruction pipe lines, a reorder buffer 6 manages information related with four instructions substantially simultaneously extracted from a main storage device by an instruction fetch part 1. The extracted four instructions are simultaneously decoded by an instruction decode part 2, and executed in parallel by ALU41-44 under the arbitration of an instruction issue controlling part 3. For example, when any hardware failure is generated in the ALU44, a failure history flag 34 is set.  When the failure history flag 34 is set, the instruction issue controlling part 3 controls the instruction fetch part 1, instruction decode part 2, and ALU41-44 for re-executing the instruction by using the ALU41-43 in which any failure is not generated according to the information related with the instruction at the time of the generation of any failure managed in the reorder buffer 6.

Title: Fuel tank
Inventor: MIKI OSAMU
IPC: F16K24/00
Filed: 1991-06-18
Abstract: PURPOSE:To reliably prevent leakage of fuel oil even when oil is fed up to a level in the vicinity of the top end of a filler pipe. CONSTITUTION:By locating a seal valve 5 to allow ventilation of a breather tube 4 through interference with a covering cap 3 to the branch base end part of the breather tube 4, the rise of an oil level in a tank main body 1 is limited through disconnection of ventilation of the breather tube 4 during the feed of oil. Through operation to cover with the cap 3, ventilation of the breather tube 4 is restored and an oil level is released from a limit and an oil level in a filler pipe 2 is lowered in a chain wise manner, whereby leakage of oil is completely prevented from occurring.

Title: Traveling control device of vehicle
Inventor: ITO HAJIME
IPC: B60K31/00
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a traveling control device of vehicle so as to prohibit a return to a constant speed traveling control when specified conditions under which a return to a set vehicle speed is not appropriate are satisfied. SOLUTION: A vehicle speed is detected by a vehicle speed sensor 10, a distance between a vehicle and a preceding vehicle is detected by a radar sensor 26, and the detected data are input into a calculation device 14. Also a set speed for constant speed traveling control and a set vehicle-to-vehicle distance for follow-up traveling control are input from a set switch 12. Then, based on the road information obtained from a map database 28 and the vehicle positional information obtained from a navigation device 30 in the constant speed traveling or follow-up traveling, for example, when a vehicle enters into the ramp way of a highway, the calculation device 14 cancels the constant speed traveling control if it is not considered appropriate to maintain the constant speed traveling control or change over from the follow-up traveling control to the constant speed traveling control.

Title: Laser beam convergence control in treatment of material
Inventor: PETERS CHRISTOPHER NICOLAS DAV
IPC: B23K26/00
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To perform correct positioning of the beam conversion. SOLUTION: When a work to be welded is irradiated with the laser beam, the plume of the optical radiation is generated. An equipment and a method are provided where the radiation from the plume is feedback received through a beam feeding passage comprising optical elements L1, L2 having chromatic aberration. The focal point of the spectral band with different plume radiation is changed thereby. An opening for judgment is formed by a surface of an optical fiber 3. After passing the fiber, the plume radiation is separated from either laser beam radiation, and each power 5 of the different spectral bands is measured. The error signal is obtained through subtraction, and used to control the focal point of the laser beam.

Title: Single phase reversible ac/dc converting circuit
Inventor: TAKAHARA HIDEAKI
IPC: H02M7/757
Filed: 1981-09-18
Abstract: PURPOSE:To simplify a surge absorbing circuit and to enhance the efficiency of a single phase reversible AC/DC converting circuit by connecting a series circuit of thyristors of anti-parallel connection and a condenser between AC terminals of the converting circuit. CONSTITUTION:A single phase reversible AC/DC converting circuit using GTO1-4 is composed, two thyristors 21, 22 of anti-parallel connection and a condenser 23 are connected in series with each other, thereby forming a surge absorbing circuit, which is connected between AC terminals of the converting circuit. In this manner, the energy contained in the inductance 18 of the circuit at the time of interrupting the current is alternately stored temporarily in the condenser 23, thereby forming the circuit having less loss. Thus, the condenser 23 can be commonly used in each GTO, thereby reducing excessive circuits.

Title: Electronic computer
Inventor: SUZUKI KATSUHIKO
IPC: G06F9/48
Filed: 1988-06-14
Abstract: PURPOSE:To prevent a program from being executed abnormally with an NMI signal by inhibiting a nonmuscle interruption signal from being inputted with a reset signal, inhibiting the input continuously even after the reset signal is reset, and permitting and inhibiting the nonmuscle interruption signal by a program. CONSTITUTION:When the reset signal is significant, a nonmuscle interrupt (NMI) signal permitting and inhibiting circuit 7 inhibits the NMI' signal from being outputted without reference to the state of the NMI signal. Further, the output inhibition of the NMI' signal is allowed even after the reset signal is reset. Then the NMI' signal is allowed to be outputted for the 1st time with a control signal from a CPU 1. Then the output of the NMI' signal is allowed or inhibited with the control signal from the CPU 1. The control signal from the CPU 1 to the NMI signal permitting and inhibiting circuit 7 is controlled by software. Consequently, program abnormal processing by the CPU 1 with the NMI signal before the leading address of an NMI processing program is transferred to a RAM 3 is prevented.

Title: Digital signal processing circuit
Inventor: TAKASHIMA MASATOSHI
IPC: G11B20/22
Filed: 1992-05-12
Abstract: PURPOSE:To obtain a high grade image even if emphasis/de-emphasis is executed in VTR, etc., by providing an overflow limiter within a negative feedback circuit and making it hard to generate waveform distortion even at the time of nonliner-processing a digital signal. CONSTITUTION:At the time of recording, data delayed by one clock by a delay circuit 12 is delayed by one clock by a delay circuit 13 and inputted into an adder 7. The adder 7 digital-adds the output from a delay circuit 11 of a feedback circuit and the output of the delay circuit 13. But, emphasis processing 15 is executed at the time of recording in a state where the coefficient K of an amplifier 3 is positive at the time of emphasis and negative at the time of de-emphasis. Next, at the time of reproducing, a digitalized chroma signal is inputted to a subtracter 6 and data is fed-back from the output of the overflow limiter 5, passes a switch 1, a 1H delay circuit 2 and a delay circuit 10, and is added with the outputs of the delay circuits 12 and 13. Thus, it is made hard to generate waveform distortion even at the time of nonliner processing the digital signal.

Title: Manufacture method of complementary thin film transistor
Inventor: TANAKA KEIJI
IPC: H01L21/8238
Filed: 1990-06-04
Abstract: PURPOSE:To eliminate the need for an ion implantation process and hence simplify a manufacture method by further delaying an etching rate of a first conductor type silicon film than an etching rate of a second conductor type silicon film. CONSTITUTION:The remaining photo resist films are used as mask 61 and 62. An n type amorphous silicon film 104 exposed from the masks 61 and 61 are eliminated by selection etching. A 'reactive ion etching process' which uses CCI2F2 and oxygen, is very popular as an etching process adopted in this case. In the case when the reactive ion etching process is adopted, the etching rate for the n type amorphous silicon film 104 is often found to be faster compared with the etching speed for a p type amorphous silicon film 102. Therefore, under the condition where the exposed n type amorphous silicon film 104 is continuously etched until a glass substrate is exposed, the etching rate for the p type amorphous silicon film 102 is extremely delayed.

Title: Porous propellant particle and its production
Inventor: JIYON EFU PIETSUTSU
IPC: C06D5/00
Filed: 1988-06-14
Abstract: PURPOSE: To enable the generation of a large quantity of gas at a speed which can be attained for many purposes by mixing predetermined quantities of at least two combustible materials, a material which can quickly interact to produce a gas product and a liquid dispersant to form a slurry, and flash-drying the slurry to evaporate the dispersant and form porous propellent particles. CONSTITUTION: A liquid composite where a solid is equally dispersed is formed into a slurry by a dispersant, in which a combustible solid reactant agent is partially dissolved. The reactant agent, for example, has alkali metal azide and a metallic oxide. A liquid component of the slurry material is quickly evaporated to forcedly discharge a liquid from the mixture, thereby leaving a network structure of passages of a hole when the liquid is discharged from the propellent particle. When a hardener is added with the liquid dispersant to the slurry composition, the strength and stability can be given to the obtained porous propellent particle. The porosity of the propellent can give enough combustion surface in the particle so as to produce such a required quantity of gas as to expand a passenger's air bag of an automobile.

Title: Earthquakeproof material
Inventor: TAKEDA MASASHI
IPC: C04B26/26
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To effectively utilize reduced slag which has been conventionally disposed to solve a problem accompanied with reclamation and supply it at a low cost by mixing a specific volume of reduced slag with a specific gravity adjusting material to obtain a specific bulk gravity. SOLUTION: Reduced slag and iron oxides must be mixed at a ratio of 10 to 60 vol.% of reduced slag and 10 to 60 vol.% of iron oxides. If an amount of reduced slag is smaller than 10%, sufficient earthquakeproof effect cannot be obtained, and if it exceeds 60%, this earthquakeproof material cannot withstand a weight of a structure. Bulk specific gravity of the earthquakeproof material must be 2.6 to 2.8. If it is smaller than the specified value, the earthquakeproof material cannot withstand the weight of the structure, and if it is larger than the specified value, the material absorbs energy so that the earthquakeproof effect cannot be obtained sufficiently. Preferably, the particle size of reduced slag is same as that of a specific gravity adjusting material, preferably less than 50 mesh, and containing particles of below 200 mesh more than 50 pts.wt.

Title: Aligning device for bar-form parts
Inventor: HIRUMA TAKAFUMI
IPC: B65G47/14
Filed: 1985-07-04
Abstract: PURPOSE:To perform the alignment of bar-form parts so easily and accurately, by setting up a cylindrical wall on an outer circumference of a tilted feeder disc with an annular parts aligning clearance, while situating a starting end in the specified position of the aligning clearance, and setting up a parts takeout guide in this part. CONSTITUTION:When a lot of bar-form part 6 or a cap having a pumping function to be attached to a bottle are thrown onto a tilted feeder disc 2, these parts 6 move in both radial and rotational directions by rotation of the disc 2, and most of them are aligned in a state of being slung between the outer circumferential part of the disc 2 and a cylindrical wall 4. And, they receive the air pressure jetted out of an air nozzle toward a conveying direction inside the aligning clearance 3 and thereby transferred, then discharged out of a takeout guide 5. At this time, the said guide 5 situates the starting end in a position between -30 deg.-150 deg. in the rotational direction of the disc 2 with a topmost part of the aligning clearance 3 as a criterion, thus the smooth takeout of these parts 6 is made attainable.
